What event leads to Gulliver being dismissed from the Lilliputian court?

The event that leads to Gulliver's dismissal from the Lilliputian court is indeed his failure to support the war against Blefuscu. This is significant because Gulliver, who initially helps the Lilliputians by defeating their enemies and serving them with his strength, faces a turning point when he expresses a more diplomatic view toward conflict. His objection to the war and failure to actively participate in it goes against the Lilliputians’ desire for loyalty, especially in matters of national pride and military engagement.

In Lilliput, loyalty to the emperor and the state's decisions is paramount, and Gulliver's stance is viewed as a betrayal. His refusal to support the war reveals a deeper questioning of the absurdity of such conflicts, which aligns with the broader themes in "Gulliver's Travels" related to the critique of human nature and politics. This act of defiance illustrates how his perception of morality and reason clashes with the absurdity of the Lilliputian political system, ultimately leading to his fall from favor.
